Answer:
What you are doing wrong is that you are using the formula to find the area of the entire circle rather than using the formula to find a sector of a circle. The two cases uses 2 different kind sentences of formulas.
(1/2)/12=1/24. So A is correct. There is no difference between A and B... F is also correct....we multiply 12 by 2 to get 1 cup per 24 muffins.
We are given two points on the line. Using these points first we need to find the slope of the line.
The points are (-8,0) and (1,5). The slope(m) of the line will be:

Using the slope and a point (-8,0) we can write the equation in point slope form as:

In standard form, the equation will be:
5x - 9y = - 40
I would divide 14.5 by 1.25
That gives you 11.6. Round that up to 12 containers
